IMPROVEMENT m DRAW-BAR ATTACHMENTS FOR am Specification forming part of LettersPatent No. 208,994, dated October 15,1878; application ,l.

To all whom it mayiconcer'n:

Be it knownthat I, JARED-H. SMTTT, "of Norwich, New London county, Connecticut, have invented an Improved- Draw-Barf Attachment, of which the'following is a specifi cation: Y I

'My invention is'an improved-attachment' for draw-bars, constructed as fully described hereinafter, so as to secure a cheap,-stron'g,

and durable attachment of the bar-to thecar,

and yet facilitate its removal.

In the drawings which form part-of this .spccificatiomFigure 11's adraw-head withiny" improvement; Fig. 2, a view showing the at jtachment Fig. 3, views showing parts ofthe attachment; Fig.4,the end ofthe drawfbar adapted to my improvement, Fig. 5,a de tached view of the key; and' Fig. 6,-a' defachedview showing the ring. t 7

Draw-bars are usually provided at their rear ends with keys or nuts, which,bearing against;

a cross-beam, bar, follower, plate, or othe'rob- 'ject, prevent the bar from being drawifforward, and sustain the entire draft of the car. The cross-pins, being of comparatively s'niall size, are apt toflupset or break under severe strains, or to become loose or'fly out of place from jarring. The nuts are likewise apt to become loose from the same cause, whileboth the pin and nut, when once fixed or set in -place, are very difiicult to remove, the removal of the nut being impossible when the end'of the draw-bar is jammed back against a beam or becomes battered, as is frequently the case.-

i To avoid these difficulties, I form upon the end of the draw-bar A an enlargement, a, which can be passed through the openingsin the follower-plates b or in the beam, andthrough thespring of rubber or. other material c. .Between the enlargementand the fol-' lower or beam .1), I apply a divided clamp'or sleeve, 1), constructed in any suitable man-- the SBGtiOlLtLSYith secured between the ner, that shown cons'i'stingof two sections, (1" -d, hingedjor loeked' 'to'gether.
